Review VWC

The following notebook is a series of figures and tables to review volumetric water content (VWC) as estimated by Hesham using "representative" bulk density values with VWC values estimated by Bryan Carlson using bulk density values taken in 1999.

The term "legacy" values refer to those estimated by Heshram. The term "revised" refer to the values estimated by Carlson.
